When I was young and living at home I remember that at home we always had a small Gingko plant in a flower pot on our terrace. The Ginko is originally from China but I always associated East Asia and Japan.
We saw many Ginkgo trees at the castle.
It is an ancient plant. Here is what ChatGPT says: “Ginkgo biloba is a type of tree that is native to China and is considered a living fossil because it has remained unchanged for over 200 million years. Its leaves contain compounds that are believed to have medicinal properties, and it is commonly used in traditional medicine to improve memory and cognitive function.“
